Yes, your computer should be able to run the x64 version of windows. Just be cautioned that there aren't a lot of drivers out there for it, so it might not be worth it if you have to buy all new equipment to get it to run right. I was foolish and bought it about a year and a half ago when i built my main box, and figured it was the next thing and i wouldn't have to wait for drivers. Well, i uninstalled it about a month later and it sits there collecting dust. I did notice it was slightly faster than the 32 bit version, but the pitfalls of not having my hardware work turned me off.
